call p%smoothers_build(a,desc_a,p,info[,amold,vmold,imold])
This method builds the smoothers and the coarsest-level solvers for the multilevel preconditioner p, according to the requirements made by the user through the methods init and set, and based on the aggregation hierarchy produced by a previous call to hierarchy_build (see Section 5.3).
Arguments
a | a >>>>>> development
class="cmtt-12">type(psb_xspmat_type), intent(in). >>>>>> development
class="cmr-12">The sparse matrix structure containing the local part of the matrix
to be preconditioned. Note that x must be chosen according to the
real/complex, single/double precision version of AMG4PSBLAS
under use. See the PSBLAS User’s Guide for details [20]. desc_a desc_a >>>>>> development
class="cmtt-12">type(psb_desc_type), intent(in). >>>>>> development
class="cmr-12">The communication descriptor of a. See the PSBLAS User’s Guide
for details [20]. info info >>>>>> development
class="cmtt-12">integer, intent(out). >>>>>> development
class="cmr-12">Error code. If no error, 0 is returned. See Section 7 for details. amold amold >>>>>> development
class="cmtt-12">class(psb_x_base_sparse_mat), intent(in), optional. >>>>>> development
class="cmr-12">The desired dynamic type for internal matrix components; this
allows e.g. running on GPUs; it needs not be the same on all
processes. See the PSBLAS User’s Guide for details [20]. vmold vmold >>>>>> development
class="cmtt-12">class(psb_x_base_vect_type), intent(in), optional. >>>>>> development
class="cmr-12">The desired dynamic type for internal vector components; this
allows e.g. running on GPUs. imold imold >>>>>> development
class="cmtt-12">class(psb_i_base_vect_type), intent(in), optional. >>>>>> development
class="cmr-12">The desired dynamic type for internal integer vector components;
this allows e.g. running on GPUs. |
